 Excellent value - Works as advertised | | Review Date: January 20, 2007 | | Reviewer: Chris P. Christensen, | | This jewel is very light to pack a 50Amp punch. I connected it to a battery insufficient to turn over the starter. The guy working on the house left his light on in the truck bed. I connected the charger to the battery while in the 2Amp mode, then plugged the battery charger into the 120VAC receptacle. I then switched it to the 50Amp selection and allowed to charge the battery for 4-5 minutes. While the charger was still connected to the battery, the guy was able to start his truck. Man was I blown away. Following the instructions, I changed the charging selection switch to the 2Amp mode, disconnected the charger from the 120VAC receptacle, and then disconnected it from the battery. How sweet - no arcing, no sparking. This is a must have!!! Excellent value and quality. |
Excellent product - excellent price | | Review Date: March 17, 2007 | | Reviewer: Ken Nerad, Walker, MN USA | | I purchased this to replace the Schumacher battery charger that I had for 30+ years when I discovered that the leads had gotten hard and cracked exposing both the 110 v. and the 12 v. wires. I did a lot of research and found this to be the best value, free shipping and no sales tax in addition to a low purchase price. It is now on the shelf for use in next emergency situation. |
Completely satisfied | | Review Date: February 9, 2007 | | Reviewer: D. M. Smith, L.I, New York | | This unit works completely as advertised, and I couldnt ask for any other features at this price. This will keep a battery in your classic car ready at a moments notice with no worry of over charging. Connect it and forget about it until the car is needed. A great charger at any price. I highly recommend it. |
Best Value You Will Find | | Review Date: June 11, 2007 | | Reviewer: Ronnie L. Nichols, | | Except for an old used service station charger that was given to me, I have never owned anything but Schumacher chargers, and have never had one to fail. The old Schumachers that were replaced with newer models with upgraded features were all handed down and continue to serve family and friends. I ordered a model SE-5212A several months ago, and was very impressed with the upgraded features, especially the over-charge protection. This feature is a real worry-free way to keep a full charge on my lawn equipment batteries, my boat batteries (including conventional deep cycle and starting batteries). I have not had a need to use the 50 amp start feature on an auto battery, but I did use it on a small garden tractor battery. The tractor engine started with nearly no effort. I really believe this is the best charger for any of us do-it-yourselfers regardless of price. I was so impressed, I just ordered a second one so I can keep one in the garage and the other in a detached shop. |
schumacher se-512a battery charger | | Review Date: December 6, 2008 | | Reviewer: Eugene A. Crandall, Rochester, NY | | The charger works good. It does work fine at automatic & doesn't avercharged the battery. |
Does the job I bought it ti do !! | | Review Date: March 25, 2009 | | Reviewer: Ronald D. Malone, Pacific Northwest | I have two of these chargers and neither one has ever failed. I have a boat, two RV's and several vehicles to maintain so one or both is always in use.
If you're looking for a charger to maintain batteries or for that occasional "quick-charge" I highly recommend the Schumacher SE-5212A Automatic Handheld Battery Charger !! |
schumacher se-5212a battery charger | | Review Date: June 30, 2007 | | Reviewer: v from tampa, florida | | Great value for the money.I bought this item to charge my ridding mower,but I've already charge my truck battery, my wife's car battery and jump started my neighboor's car.It works great, a good namebrand charger that is going to last you for a long time. |

Schumacher Automatic Charger | | Review Date: April 1, 2010 | | Reviewer: Gingus Khan, lllinois & Wisconsin | | Great product; the previous one I had lasted 20 yrs ... The automatic shut off featue is a must; this way you can leave it on overnight without worrying about overcharging. It doesn't seem there is much difference in price for the models with automatic and those without. I have a number of toys (boat, ATV, snowmobile) that may sit idle for weeks; the 50 amp starting feature if perfect to get things started when its cold and the battery is low. |
battery charger | | Review Date: April 27, 2010 | | Reviewer: K. E. Warrenfeltz, usa | After reviewing a number of charger this one is the best
I have found and meets my criteria.
price was acceptable and features as I wanted. |
Very Dependable | | Review Date: April 29, 2010 | | Reviewer: Carmen Collins, | | I bought this for my son and he really loves it. It works really fast. |
a good charger | | Review Date: February 22, 2010 | | Reviewer: Michelle M. Ress, Felton, CA., USA | I've been using this charger for years to keep my starting/deep cycle batteries charged and it has done that job well. I've also used it on occasion to start a car with a dead battery and it does that well. I would buy this brand and model again and recommend it.
Update: I'm about to buy another one for the battery in the house that I use to power my Kenwood amateur radio transceiver. It's an excellent charger.

Battery Charger | | Review Date: May 25, 2010 | | Reviewer: Duane R. Harper, Virginia | | Works great. Automatic mode is great to get the most charge into the battery. |
Battery charger. | | Review Date: August 7, 2007 | | Reviewer: Palmer Smith, | | I have only used this about three times, but it is great. I need the automatic shut-off because I am forgetful. It charged a large tractor battery in less than 12 hours. The two amp feature is nice for my lawn mower battery. I have not tried the jump-start feature, but I will this winter. Appears to be well made and should last me the rest of my life. |
Schumacher SE-5212A Handheld Automatic Battery Charger | | Review Date: October 9, 2007 | | Reviewer: William O. Denham, | | This is a terrific little battery charger. It has done everything it was advertised to do. I have an old pick-up truck that sits for weeks at a time between uses and I leave the charger connected to ensure that my truck will start. It has every time. |
Perfect addition to my garage | | Review Date: January 22, 2007 | | Reviewer: Mark S. Koehler, Chicago, IL | | I would have given it 5 stars, but did not have the opportunity to evaluate the 50A charge/start mode. Overall this unit functions perfectly, and its light weight and ample AC cord and battery cable length make it easy to hook up and use. I have used other chargers previously, but none had the automatic shut off and trickle charge modes. |
Works great; 2 amp mode puts out MORE than 2 amps! | | Review Date: April 12, 2009 | | Reviewer: Rion, Alameda, CA USA | I bought this unit back in 2002 for those rare dead battery situations and so it has sat around unused for the majority of that time. Recently I have been trying to revive a troubled battery and have been using it more often - typically a few minutes every day. It has served me VERY well. One complaint I heard elsewhere was regarding the lack of a light for the meter, which I will echo here. It does seem odd that they have a power-on LED, but no light for the meter itself.
One little concern that hasn't really been a problem for me is that fact that it WILL put out much more than 2 amps in the 2 amp charging mode. I have a Fluke digital ammeter and have checked the charger on a few occasions now when charging batteries. The 2 amp mode has been normally putting out between 3 and 6 amps. The manual (which covers 3 different models) is not real clear about this, so I thought I would elaborate. Between reading the manual and my own observations, I will say that the 10 amp mode starts out at 10 with a drained battery and tapers off down to 5 amps (when it will automatically shut off), whereas the 2 amp mode seems to start as high as 7 amps and tapers down to .34 amps(and shuts off). |
Good product | | Review Date: March 14, 2010 | | Reviewer: Mark Twain, | | As others have written, it really should have a backlight on the meter, but other than that a good product. |
Great product except... | | Review Date: June 30, 2007 | | Reviewer: Banes, | I have a slow drain on my car's battery. If I leave the car sitting for half a day, the battery will be completely dead. I bought this device and I realized after it came that I'd have to take the battery out every night to recharge the battery, which is very annoying. Fortunately, in many Cadillacs the battery is located under the rear seat and is very easy to access. I live in an apartment and do not have a garage so I can't run an extension cord to the outlet and then connect it to the charger while the battery stays in the car. Whoever wrote the product description should not have assumed that all buyers are male homeowners. A female renter would most likely have a very difficult time disconnecting the battery and carrying the heavy thing up to their apartment to charge it.
About the charger features, it works very efficiently, but the 'fully charged' indicator on mine was faulty. The only way I knew the battery was fully charged is because I wiggled the positive clamp a little and the 'fully charged' light would flicker and then shut off. It charges pretty fast no matter what your setting is. It's also very lightweight. Clamps are small and sturdy. The cords are lengthy enough to prevent touching/spark.
Suggestion: If you are an apartment/condo-dwelling Cadillac owner, just disconnect the positive battery terminal under the rear seat after you use your car to prevent the parasitic drain. Your battery will maintain its charge for weeks of no driving if it's disconnected. You do not need this product AT ALL. What I did was went ahead and bought the Mighty Mite (5 stars) for MAXIMUM assurance that I won't be stuck with a dead battery. I'm on my way to the Mighty Mite page to give that product 5 stars. |
Charger failed after 3 months. I think there is a UL violation here. | | Review Date: February 3, 2009 | | Reviewer: DrD, Phoenix, AZ | I bought this charger 3 months ago and it failed this morning when I plugged it in. There was no load on the charger as the alligator clips were well separated and definitely not short circuited. Being an engineer I took the cover off, traced the circuit diagram and ohmed-out the transformer to find that the transformer had failed. It is not repairable.
UL approval requires that the hot wire of the power line first go to a circuit protection device (fuse or circuit breaker). There is no visible fuse or circuit breaker in the 120V circuit. The hot power wire goes directly to the transformer, which is a gross UL violation, unless there is a fuse inside the transformer, which I cannot determine since it is a sealed unit. The neutral wire goes to a switch which chooses different transformer taps for different output current settings. Thus, it appears that the 120V circuit must be protected by the house circuit breaker.
A small point, the 50 amp. output is unlikely since there is a 35 amp. 12 volt breaker in series with the negative DC output lead. This, of course, does not protect the AC side of the circuit.
Be very careful with this product as it may be a fire waiting to happen. If you own one I suggest that you place it on a concrete floor far away from any combustible materials. Do not place this unit on a wooded work bench while plugged in to AC power. |
